I'm gonna go out on a limb here. The ones that have been mentioned are good. Later Eps of Smallville are really good. But I would like to point out a sleeper that caught me by surprise. For about 6 months, I was living with two girls and another guy in a shared house. And the girls were really into this show. At first I was thinking "another chick show..." Then one day I was in a conversation with them when the show came on. They politely asked if we could finish talking when the show was over. I said sure. So I watched an ep. Things I was impressed with:
the situations - stuff you don't see on normal TV... well kinda... it was like the writers would take the mundane and dive so far into it that it came out weird. Sort of the mirror image to Science Fiction, weirdness through the known rather than the unknown.
the dialogue - while not realistic, it was amasingly clever. Very call and response-ish. But with emotion. there was a constant sas to it.
this was not a "weird episode" either. It was like this every week. this was a show that jumped the shark at day 1. And makes a point to jump the shark regularly and often. It might as well be called "jump the shark." Pure genius.
Well developed characters - if not stereotypical. In a sort of Alice in Wonderland sort of way.
I absolutely fell in love with (well, I wont buy it, but...) The Gilmore Girls when they added Sebastian Bach from Skid Row as a burnt out metal head regular to the shows emo-inspired teen band. At that point I was like "Don't fire your writers, EVER."
Sue me for liking a chick show and posting about it here. But its a really well done program.
